EC number: 268-074-9
CAS number: 68002-61-9
This substance is identified by SDA Substance Name: C16-C18 and C18 unsaturated alkyl trimethyl ammonium chloride and SDA Reporting Number: 11-045-00.
The surface tension of the test substance,
C16-18 and C18-unsatd. TMAC (purity not specified) was determined using
ring method according to DIN 53914 and ISO 340:1985.
Critical micelle concentration was determined using an automated
tensiometer (KSV Tensiometer Sigma 70) connected with a computer. The
water used was distilled and deionised using a MilliQ® plus purifier
from Millipore. The tensiometer was calibrated with distilled water
(surface tension value (mAV) at 25°C = > 72 mN/m). Under the study
conditions, the surface tension of the1 g/L solution of the test
substance at 25°C was found to be 33 mN/m and the critical micelle
concentration was found to be 0.14 g/L at pH 7.0 (Borjesson, 2012).
surface tension of the test substance was determined using ring method according
to DIN 53914 and ISO 340:1985 (Börjesson J, 2012).
